Halliburton will plead guilty to a charge of destroying evidence related to the Deepwater Horizon disaster of 2010 in the Gulf of Mexico. The company will pay the maximum $200,000 statutory fine under the deal, face three years of probation, and be required to continue to participate in a federal investigation.

Halliburton helped with the cementing process for the drill site. That involves placing a number of "centralizers," or metal rings, to aid the cementing along. And while the site should have used 21 centralizers, the Deepwater Horizon rig had just six — a decision made by BP, against Halliburton's recommendation. Halliburton, according to the press release from the Justice Department on the plea agreement, then set about destroying two computer simulations showing little difference between the use of six and 21 centralizers after criminal investigators from the Deepwater Horizon Task Force began to zero in on the cementing process. Halliburton is also giving $55 million to the National Fish and Wildlife Foundation as a voluntary part of the agreement.
